Can Köln lay a glove on Bayern?

1. FC Köln's superb start to the season may have caught a few sides, fans and pundits off guard, but it faces the ultimate test on Matchday 6. FC Bayern München lie in wait to give coach Peter Stöger's troops their sternest examination yet, and the rest of the Bundesliga will be keen to find out whether the Billy Goats can be the first team to really land a punch on the defending champions this season. Both sides struggled on Matchday 5, and Bayern tasted defeat in the UEFA Champions League in midweek, so their respective approaches to this one will be fascinating.
